HAMMER.

SPECIFICATION forming part of Letters Patent No. 602,971, dated April26, 1898.

Application filed August 6, 1896.

T0 and whom it may concern:

Be it known that I, LELAND GRANT YOUNG, a citizen of the United States,residing atMuscatine, in the county of Muscatine and State of Iowa, haveinvented a new and useful Hammer, of which the following is aspecification.

The invention relates to improvements in hammers.

The object of the present invention is to improve the construction ofhammers and to provide a simple and inexpensive one which will carry asupply of tacks and which will automatically feed a tack in position tobe struck by the hammer-head.

A further object of the invention is to provide a supplemental orauxiliary head for t-acks' to increase their holding power and tofacilitate the tacking of cards at an elevation without the use of astep-ladder or other support by providing means for holding a card onthe hammer in position to receive a tack.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a hammer constructedin accordance with this invention. Fig. 2 is a longitudinal sectionalView of the same, the hammer being thrown forward. Fig. 3 is atransverse sectional View. Fig. 4 is a longitudinal sectional view online 4 4 of Fig. 2. Fig. 5 is a detail perspective view illustrating thearrangement of the resilient pawls and showing the pawl of the feed-barin position for advancing the tack-carrying strip.

Like numerals of reference designate corresponding parts in all thefigures ofthe drawings.

1 designates a tubular stem forming a tackholder or magazine andprovided at its inner end with asocket 2 for the reception of a handle3, which may be of any desired length to give the hammer sufficientreach to enable a placard, bill, or the like to be tacked at the desiredelevation. The stem or tack-holderis substantially semicylindrical andis provided at its straight or flat side with a central longitudinalgroove 4 to receive the shanks of tacks 5, and it is provided atopposite sides with flanges 6, extending from the flat side or back ofthe tubu- $erial No. 601,881. (No model.)

lar stem or tack-holder and forming a way for the reciprocating feed-bar7, which is adapted to advance the tacks successively to a point justbeyond the outer end of the tack-holder in position for them to bestruck by an oscillating hammer-head 8. The hammer-head S, which islocated at the outer end of the tackholder or magazine and which isarranged to move transversely thereof, is fixed to an oscillating arm orbar 9, which is hinged at its inner end to the tubular stem ortack-holder adjacent to the inner end thereof, the tubular stem ortack-holder being provided with perforated cars 10 for the reception ofa pivot, which also passes through theinner end of the arm or bar 9. Thearm or bar 9 is supported by a substantially rectangular keeperll,disposed transversely and extending from the tubular stem or tack-holdernear the outer end thereof. The hammer-head is held raised in positionfor driving a tack by a spring 12, interposed between the arm or bar 9and the tubular stem or tack-holder and preferably secured to theformer; but it will be apparent that it may be attached to either of thesaid parts.

When a tack is fed from the tack-holder or magazine to a position inadvance of the outer end of the same, the entire device is swung similarto an ordinary hammer in striking a blow. The outer end of the hollowstem or tack-holder comes in contact with the surface into which thetack is to be driven; but the hammer continues its movement after thetubular stem or tack-holder has come in contact with the said surface,striking a tack and driving it into such surface. If the force of theblowshould not be sufficient to drive the tack completely into suchsurface, the reverse side of the hammer-head may be employed to completethe tacking operation.

The tacks are mounted on a strip 13, of paper or other suitablematerial, which is inserted in the tubular stem or tack-holder throughan opening 14 at the inner end thereof, the shanks of the tacksextending into the (zen tral longitudinal groove and the strip of paperin the longitudinal way being received between the side flanges 6. Thisstrip, which carries the tacks, is provided at opposite sides withsubstantially \lshaped notches 15, which fixed to the tack-holder ormagazine and arranged within the way thereof, and a similaractuating-pawl 17, carried by the reciprocating feed-bar. These pawls,which are resilient and which have their forward or outer ends curvedinward, as clearly illustrated in Fig. 4 of the accompanying drawings,are arranged to engage opposite sides of the strip, which isautomatically fed inward by the return movement of the parts of thehammer after striking a blow in driving a tack. The reciprocatingfeed-bar is provided at opposite sides with perforated ears and isconnected with the oscillating bar or arm 9 by a link 19, which isdisposed at an angle to the tubular stem or tack-holder and theoscillating bar or arm 9 and interposed between the said parts. Thelink, which is substantially U-shaped, is composed of two sides,connected at one end by a transverse portion which is arranged in aperforation of the arm or bar 9, and the sides of the link at the otherend thereof are bent outward and are arranged in the perforations of theears of the feedbars. By this construction the feed-bar is reciprocatedby the oscillation of the arm or bar 9 independent of the tubular stem.When the oscillating bar. or arm 9 moves forward independently of thetubular stem in striking a blow, the feed-bar is moved inward and itsactuating-pawl engages a notch at the adjacent side of the strip and thereturn movement of the hammer carries the feed-bar outward, whereby thestrip of tacks is fed forward. The resilient check-pawl engages thestrip of tacks and prevents it from .moving inward with the feed-bar.The feed-bar is provided at opposite sides with flanges receiving thestrip of tacks between them and fitting in longitudinal grooves locatedat the opposite sides of the central longitudinal groove of the tubularstem or tack-holder. The grooves and the way of the stem or tackholderare preferably formed by longitudinal strips arranged parallel to formthe central longitudinal groove and having their outer longitudinaledges angularly bent and inwardly offset to form substantially L-shapedflanges, the lateral portions thereof forming the bottoms of the sidegrooves and connecting the strips and sides of the tubular stem belowthe upper edges thereof. The tubular stem or tack-holder is provided atits outer end with a back portion 20, which connects the flanges 6 andwhich assists in retaining the feed-barin its longitudinal way, and itis also engaged by the free end of the spring which raises thehammer-head.

The forward end of the hammer-head is arranged at a slight angle toprovide a cutting edge 21, which passes over the outer end of thetubular stem or tack-holder, making a shear cut and. adapted to sever aportion of the strip 13, and the severed portion of the strip remains onthe tack, forming a supplemental head to increase the holding power ofthe tack.

The tubular stem or tack-holderis provided at its front side with a flatspring 22, secured at its inner end and having its outer end free,whereby it forms a clip adapted to receive and support the lower edge ofa card to hold the same in position for tacking it. This clip or supportwill enable a card to be attached to the device, and the hammer, beingof considerable length, will enable the card to be tacked on a fence orother support at an ele- Vation from the ground to be out of the reachof children. At opposite sides of the tubular stem or tack-holder arearranged sockets 23, receiving rods 24, which are provided at theirouter ends with hooks for supporting a bill or similar paper in positionto be tacked. The rods are removable and when not in use may be takenout of the socket, so as not to interfere with the use of the hammer forany purpose.

It will be seen that the hammer is simple and comparatively inexpensivein construction, that it is automatic in operation, and that the tacksare positively fed forward simply by the movement of the hammer instrikinga blow. It will also be apparent that the strip on which thetacks are mounted f u rnishes supplemental heads for the tacks toincrease their holding power.

Changes in the form, proportion, and minor details of construction maybe resorted to without departing from the principle or sacrificing anyof the advantages of this invention.
